MLS-C01 Data Engineering Practice Question
A company wants to perform real-time analytics on streaming data from clickstreams. The data needs to be ingested, processed, and made available for querying within seconds. Which AWS service should be used for the processing step?
⚠ Common exam trap
A common mix-up: candidates confuse AWS Glue's streaming ETL capability (which still relies on Spark Structured Streaming with higher latency) with Kinesis Data Analytics' native real-time processing, or they assume Athena can query streaming data directly when it only queries data at rest in S3.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon Kinesis Data Analytics
Amazon Kinesis Data Analytics is the correct choice because it enables real-time processing and analysis of streaming data using SQL or Apache Flink. It can ingest data from Kinesis Data Streams or Kinesis Data Firehose, process it with sub-second latency, and output results to destinations like Kinesis Data Streams or Firehose for further querying, meeting the requirement for analytics within seconds.
